For my preop diet the first week I could eat lean meat, fresh veggies and soups. I am allergic to milk so I stayed away from that. I have since discovered soy milk. The second week was all liquids. At the time I was given no directions so to me liquids were broths, tea, jello, sugar free popcicles, and water. I had weaned myself away from my soda habit. I also took :"shots" of pure protein that I added to water to get in my protein.
Now I realize I could have done protein shakes but that is now and then was then. I lived off a combined mixture of chicken, beef and vegetable broth blended together. I drank hot tea, cold tea and water flavored with those little powder flavor packets that are no calorie. I munched on sugar free popcicles until they were coming out of my ears. They were a godsend. After the 3rd day it was not difficult at all. It did not even bother me when other people ate at work. I just kept my goal of surgery in mind.
I wanted to really insure that I could have lap surgery. I had an open gallbladder surgery that took me 2 months to recover from and I am left with pain from adhesions to this day. There was no way I was going to be told I had not lost enough weigh or that my liver had not shrunk enough. That thought kept me going.
As for telling people, I did not tell the world. I told some close friends. I also have not met one person who has been negative about the surgery except for a sister. That really surprises me. I think there is a better understanding of the surgery today.
There will always be people that think it is your fault that you cannot loose by yourself by just dieting. However, there are scientific studies that prove that if you have over 100 lbs to lose, it is not going to happen by diet alone. However, you cannot change the minds of ignorant people. All you can do is try to educate them and/or ignore them. It is THEIR problem, not yours.
This was the best thing I ever did and I would do it again in a heartbeat! Good luck to you!
